ANATOMY The TFCC is a fibrocartilage-ligament complex which stabilizes the distal radioulnar joint (DRUJ), transmits axial load between the carpus and the ulna, and stabilizes the ulnar aspect of the carpus. The TFCC is comprised of the disc proper (articular disc), meniscus homologue, ulnolunate ligament, ulnotriquetral ligament, proximal ligamentous component, volar and dorsal radioulnar liga...

OBJECTIVE To characterize biomechanical differences in gait between dogs with and without an amputated thoracic limb. ANIMALS Client-owned dogs (16 thoracic-limb amputee and 24 quadruped [control] dogs). PROCEDURES Dogs were trotted across 3 in-series force platforms. Spatial kinematic and kinetic data were recorded for each limb during the stance phase. RESULTS Amputees had significant i...

Calyptraeotheres camposi sp. nov. is described from the Gulf of California, Mexico. The new species is close to C. granti (Glassell, 1933) and C. pepeluisi Campos & Hernández-Ávila, 2010 from the Mexican Pacific and to C. hernandezi Hernández-Ávila & Campos 2006 from the Western Atlantic. These four species feature a third maxilliped with a 2-segmented endopod palp and the exopod with unsegment...

BACKGROUND Carpal tunnel release (CTR) has been shown to change carpal arch morphology. However, the effect of CTR on the three-dimensional kinematics of the carpal bones has not been demonstrated. PURPOSE This study examined whether release of the transverse carpal ligament (TCL) would alter the three-dimensional kinematics of the carpus, specifically the bony attachments of the TCL. METHO...

KEYWORDS: kinetics, horse, locomotion. REASONS FOR PERFORMING STUDY: Equine gait analysis has focused on 2D analysis in the sagittal plane, while descriptions of 3D kinetics and ground reaction force could provide more information on the Equine gait analysis. HYPOTHESIS OR OBJECTIVES: The aim of this study was to characterize the 3D torques and powers of the forelimb joints at trotting. METHODS...
